Shiro is the mother of Capheus and his unnamed younger sister. She is incredibly close to her son and does her best to take care of him, though she is living with AIDS and without enough money to pay for treatment. She is very proud of Capheus but feels guilty that he is forced to look after her.
When Capheus was a child, Shiro fought a group of men who wanted to harm him, despite the risk to herself and her unborn child. She left the village with Capheus to protect him but unable to care for her herself, she gave up her daughter to an orphanage after she was born.
